Panic-full code library
SMC panic sensor codes by model: what to test before replacing parts
SMC sensor codes are meaningful only with the device identifier and bit position or sensor array from the original log. The same-looking panic family can route to different assemblies on different generations.
First diagnostic path
- Keep the device identifier, SMC assertion and complete sensor array together.
- Use a mapping verified for that precise model revision.
- Confirm the mapped path electrically or with a known-good peripheral.
Other causes to keep in scope
- Multiple missing sensors caused by one shared rail.
- Incorrect mapping copied from a different family.
- Connector or board damage downstream of a healthy sensor.
How CoreMatch uses this signature
The analyzer combines this token with the panic family, exact device model and compatible verified evidence. It ranks a likely component only when those signals agree, then provides confirmation steps.
Important limitation
A public code table should be a starting point, never a substitute for model verification and measurement.
